There's also the BVG Fahrinfo app, which is BVG's official transit app. This app gives really good transit directions as well as schedules. You can also buy tickets directly from the app.
==== From Tegel Airport TXL ====
* The recommended route from TXL to the office is via the S-Bahn ring. From the airport, take bus TXL to S Beusselstraße (2 stops). From there, take S41 (via Gesundbrunnen, Ostkreuz) to Treptower Park. From there the office is only 10 min walk away: go right on Puschkinallee and keep straight (it's a beautiful walk!). You can also take bus 165 (direction U Märkisches Museum) or 265 (direction U Stadtmitte ) to Taborstraße. This will leave you right in front of our office building.
==== From BER Brandenburg Airport ====
